Application filed January 2, 1883. (No model.)

To all whom 'it may concern Be it known that I, FEEDEICK C. MILLER, a citizen of the United States, and a resident gf-Newport, in the county of Campbell and Staton of Kentucky, have invented certain new and useful Improvements in Friezing Machines, of which the followingV is a specification.

My invention consists in an automatic friezing-machine for working out blocks to correspond with any desired configuration of form It is shown as especially adapted for cigar-molds. The entire machine and its several working parts will be fully set forth in the description of the accompanying drawings.

Figure 1 is a side elevation of my machine with one side of the frame removed. Fig. 2 is In order that of the other,

a rear elevation of the same. Fig. 3 is a top plan view.` Fig. 4 is a perspective view ofthe. hinged feeding device and block-pattern. Fig. 5 is a sectional elevation of the cam for driving the feeding-carriage. Fig. 6 isa detailed view of the feeding-carriage and driving-pitman. Fig. 7 is a plan view of the tripping de-i -vice for throwing out the nished block. Fig. S is a sectional elevation, showing the attachment of the carriage to the pitman.

A represents the base of the machine-frame; A', the table, mounted on the sides A".

B B' represent the shafts, upon the top of which the cutter-heads c c are mounted ,fb b', the pulleys by which they are respectively driven by pulleys upon a counter or main shaft located opposite the machine, but not shown. those cutters may work to the same `vertical line without interfering, one shaft,with its cutter-head, is placed in advance as shown in Figs. land 3.

C represents hinged or oscillating shafthangers. there being one for eachof the shafts B B'. The object of these hinged oscillating hanger-shafts is to allow the cutters c to automatically advance toward or recede from the pattern and block to be shaped.

D cl represent weighted arms hinged upon studs d ,for holding the cutter-heads up to their work. Springs might beused in lieu of weights.

E represents the form of the block to pattern, which is of the be friezed. It passes between and bears against guides e e, which are rigidly attached to the hanger-frames above the cutting-plane. The guides press against forced between the cutters c. The edges of the guides, pressing againstpthe outside face of pattern E, cause the cutters to work off the block to correspond with the shape of the pattern, the shafts b b ters swinging out or in as guided by the pattern E. Pattern E is shown as attached to a stock swiveled upon a guide-arm automatically driven between the guides 5 but so far as the operation of the laterally-yielding cutters and the mode of shaping the block are concerned the feeding may he by hand or by the feeding devices, which are also features of my invention, and are constructed as'follows:

F represents a countershaft journaled upon the machine; F', a pulley driven by one upon a main shaft, and is a`transmitter for operating the feeding mechanism.

frepresents a gear driven by pinion j" on shaft F. G represents the carriage, which isjournaled so as to reciprocate upon rod G'. 1t is operated by an oscillating arm, H, which is hinged upon shaft- F at the bottom, and its top end hinged by link l to carriage G.

H represents a brace-arm formingfpart of arm H, and projecting backward over shaft g, which carries a cam, I, upon the edge of which bears friction-roller i',journaled upon the heel of arm Il', as shown in Fig. 5. A single revolution of cam I will reciprocate carriage G both forward and backward. The shape of the cam I is such as to drive it forward slowly for friezing the block slowly and retracting or making the backward motion quickly.

I represents a weighted lever to hold roller t' against cam I.

Krepreseutsan oscillatin g forked arm, hinged by centers k upon carriage G.

L represents the pattern-stock, hinged upon one fork of arm K, to which stock pattern E is rigidly fastened for carrying the block between the cutters. In order to insert pattern E into the cup to be friezed and hold it firmly in position duringlthe cutting, and to automatically raise it to release and discharge the friezed block, and to cause it to automatically the sides of the pattern E, and the blocks are and their contained cutmounted upon the shaft ,of table A' on line n', the front orlong arm, on',

being downon the table, as shown in Fig. l., for the forward movement of the guide-arm K, thereby holding the opposite end of the arm 'K, which carries stock L and pattern E, firmly in the block while itis being slid f'orward on the table and passed between the cutters. As soon as roller m arrives at notch a on table A', friction is removed from off the face ot roller m, which has held the arm M" vertical,

and the arm M m' will rise or turn upward, as shown in Fig. 4, and the excessive weight on the outer end of arm H will cause it to turn on the centers 7c and lift pattern E out of the cavity in the cup and high enough to pass over the cutters c and guides eas the carriage G, carrying the arm K, is drawn back by the cam I, as before explained.

'N represents a spring connecting parts K and G, so as to secure an excess of pressure on the outer end of part K and on the roller in. so as to quickly throw arm K and lift pattern E above the cutters and guides.

o represents a roller journaled on a fixed stud,o, projecting` down from arm K, as shown in Fig. 4.-

P represents a vertical rod, (see Fig. 1,) the upper end of which passes through a slot in the table, and the lower c nd carries a roller resting on the edge of cam t, Fig. 5, which cam is mounted on shaft g, and of such shape as to lift rod P, so as to engage with roller o, when carriage G and feed-arm K are retracted, and force pattern E into the concave of a block, which has meantime been placed in position in front of gage-block Q, attached to the table in the line of travel of the pattern E.

The clearing device for knocking the block off of the table is preferably constructed as follows: t represents a hook made on the forward ear of carriage G, which engages with a notch, t', cut in the head of cranlr-arm T, which crank-arm isjournaled upon astud-pin tapped in table A', as shown in Figs. 3 and 7. s represents a link connecting crank-lever T to crank-bar T', the forward end of which is thrown quickly against the block whenever hook t engages notch t' and discharges the block oft' the table. The backward movement of the carriage G brings the parts T T' back into position shown in Fig. 3, ready for a secondoperation.

I claiml. In a shaping-machine, the combination of a table or bed, independent oscillating cutters driven by shafts mounted on hinged han ger-fram es, for shaping material resting directl y on the table or bed while it is passed between the cutters, and a traveling holder yarranged to press the materiall down upon the table while being shaped,substantially as described.

2. The combination of a table or bed, oscillating cutters c c', driven by shafts mounted on hinged hanger-frames, for shaping material resting directly ou the table or bed while it is passed between the cutters, the guides e e, rigidly attached to the hinged han ger-frames, between which the pattern passes, and a travcling holder arranged to press the material down upon the table while being shaped, sub-` stantially as described.

3. The combination, with the table or hed, the yielding cutters cc', and guides e e, of a reciprocatingfeeding-carriage resting directly on the table or bed, and a rocking arm mounted on the carriage and carrying a pattern, and arranged .to press the material to be shaped down upon the table or bed as said material is passed between the cutters, substantially7 as described.

4. The combination cfa table, a cutter or cutters, a reciprocating carriage, a feedingarm pivoted upon the carriage and arrange d to press the material down upon the table, and a weighted oscillating arm actuated by a revolving cam for reciprocating the carriage, substantially as described.

5. The combination of the reciprocating carriage Gr, the feedingarm K, oscillating in bearings which are parallel to the line of motion of the carriage, the'stock L, and pattern E, carried by one end of the feeding-arm, and oscillating cutters for shaping the material as it, with the stock and pattern, is passed be'- tween the cutters by the feeding-arm, substantially as described. y

6. The combination of a` table` a cutter or cutters, a carriage, and an oscillating feeding-arm for carrying the material past the cutter or cutters, the tripping-crank M m', journaled on the feeding-arm, and means,'such substautially as described, for tripping the crank.

7. The combination of the reciprocating carriage, provided with the catch t and the table or bed, with the discharging-lever T', arranged to swing in a plane parallel to the plane ofthe table or bed, the crank T, and connecting-link IOO lIO
